T 0 all whom it may concern:

Be it known that 1', JAMES VVoR'rniNGtroN, a citizen of the UnitedStates, residing at Manitowoc, county of lilanitowoc, and State ofWisconsin, have invented new, and useful improvements in Variable Speedand Reversing Gears, of which the following is a specification.

My invention relates to improvements in variable speed and reversinggears designed especially for use in motor driven vehicles butapplicable also to other uses.

The object-0f my invention is to provide mechanism ofthe described classwhich is'especially adapted for use in connection with motor drivenvehicles and which embodies a minimum number of shafts and gear wheels"arranged in a manner to be little affected by strains and jars; also toprovide a form of Structure in 'WlllCl the cost of manufacture isreduced to the minimum.

In the following description reference is had to theaccompanyingdrawing,showing a sectional view of my invention taken in a plane common to theaxis of the several shafts. l is the driving shaft and 2 the drivenshaft.- and l are transmission shafts preferably .i ged end to endwithin a three way bearing member 6, which also receives one end of thedriving shaft 1 at right angles to the transmission shafts 3 and l. Thedriving shaft is provided with a beveled gear wheel 9 which meshes withbeveled gear wheels 10 and 20 on the shafts 3 and 4 respectively anddrives the Wheels and. shafts continuously. I A pinion 11 is adapted totransmit power from the gear wheel 10 and shaft 3 to the shaft 2 throughthe ear wheel 12 and gear shifting sleeve 13, the latter being splinedto the shaft 2. A gear wheel 15 fast on the shaft 3 is adapted to,transmit a more rapid speed to the shaft 2 through the gear wheel 14,which is also mounted on the sleeve 13. T he sleeve 13 is adapted to beshifted along the shaft 2 to bring gear wheel 14 to mesh with gear wheel15, or to an intermediate position with both gear wheels 12 andld out ofmesh.

'lo reverse the motion, the shaft 2 is provided with a gear wheel 18,also mounted upon a shifting sleeve 21 splined to shaft 2 and adapted tobe shifted into mesh with and driven from a pinion 19 connected with thegear wheel 20 and shaft l. The gear wheel 18 and pinion 19 will ofcourse be brought into niesh only after the gear wheels 12 and 14 havebeen adjusted to an intermediate posi tion, out of mesh with boththepinion 11 and gear wheel 15.

The gear members above described are inclosed by a suitable casing 24provided with shaft bearings 25. The means for shifting the sleeves 13and 21 are not illustrated, since such means are common in the art, andthe specific structure and arrangement thereof is not important to theoperation of my invention and any ordinary form of gear shiftingmechanism may be employed.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is,

1. The combination of a driving shaft, a beveled gear wheel thereon, aset of transmission shafts, a beveled gear wheel on each, arranged tomesh with the beveled gear wheel on the driving shaft, transmissiongears on said transmission shafts, operatively connected with thecorresponding beveled. gear .wheel, a driven shaft, and shiftable gearwheels thereon adapted to be moved into and out of mesh with thetransmission gears.

2. The-combination with a driving shaft, and a set of transmissionshafts, of a set of beveled gear wheels, each. fast on one of saidshafts and arranged with. the one on the driving shaft meshing withthose on the transmission shafts, transmission gears, each connectedwith one of the beveled gear wheels on one of the transmission shafts, adriven shaft, shiftable gear wheels thereon adapted to be moved intoandout of mesh with the transmission gears, and a three way bearingmember arranged to support the adjacent ends of the driving andtransmission shafts.

3. The combination of a set of oppositely extending transmission shafts,beveled gear wheels thereon arranged in adjacent planes, a driving shafta beveled gear wheel thereon meshing with the beveled gear wheels on thetransmission shafts, a set of gear wheels of different size on one of 0the transmission shafts, "a gear wheel on the other transmission shaft,a driven shaft and shiftable gear wheels thereon each adapted to beselectively adjusted to mesh with one of the gear wheels on one of thetransmission shafts whenthe others are out of mesh.

4. The combination with a set of two adjacent gear wheels of a drivinggear wheel mesh with both and arranged to drive them in oppositedirections, shafts connected with the respective gear Wheels of saidset, transmission gear wheels on said shafts a trans mission shaft andslidable gear members thereon adapted to selectively engage the 5 drivengear Wheels. I

The combination with suitable supports, of a set of gear Wheels arrangedin ade'maei of the gear Wheels of said set, a lriv-sn sh l andshifts-ole Wheels mounted and adapted to be meted into and. cut ei meshwith the transmission gear Wheelsin testimony whereof Lafiix mysignature in. the presence of two Witnesses.
